+Overview
+========
+
+This software package provides basic support for
+Intel(R) Resource Director Technology (Intel(R) RDT) including:
+Cache Monitoring Technology (CMT), Memory Bandwidth Monitoring (MBM),
+Cache Allocation Technology (CAT), Code and Data Prioritization (CDP)
+and Memory Bandwidth Allocation (MBA).
+
+In principle, the software programs the technologies via
+Model Specific Registers (MSR) on a hardware thread basis.
+MSR access is arranged via a standard operating system driver:
+msr on Linux and cpuctl on FreeBSD. In the most common architectural
+implementations, presence of the technologies is detected via the
+CPUID instruction.
+
+In a limited number of special cases where CAT is not architecturally
+supported on a particular SKU (but instead a non-architectural
+(model-specific) implementation exists) it can be detected via brand
+string. This brand string is read from CPUID and compared to a table
+of known-supported SKUs. If needed, a final check is to probe the
+specific MSR’s to discover hardware capabilities, however it is
+recommended that CPUID enumeration should be used wherever possible.
+
+From software version v1.0.0 the library adds option to use Intel(R) RDT via
+available OS interfaces (perf and resctrl on Linux). The library detects
+presence of these interfaces and allows to select the preferred one through
+a configuration option.
+As the result, existing tools like 'pqos' or 'rdtset' can also be used
+to manage Intel(R) RDT in an OS compatible way. MSR interface remains
+the default option for now. 'pqos' tool wrappers have been added to help with
+the interface selection. 'pqos-os' and 'pqos-msr' for OS and MSR interface
+operations respectively.
+
+PID API compile time option has been removed and the APIs are always available.
+Note that proper operation of these APIs depends on availability and
+selection of OS interface.
